Relative Gene Expression Analysis

Relative quantification by PCR is a valuable tool for measuring gene expression levels. This approach relies on the comparative Cq method and gives a relative value of target molecule abundance.

Relative quantification is the method of choice to study the abundance of multiple targets in parallel. Because this analysis requires fewer control samples for quantification compared to absolute quantification methods, it is optimal for increased throughput. This type of analysis can be carried out either using intercalating dye- or probe-based detection, with different advantages and disadvantages for each approach.

At PCR Biosystems we carefully engineer qPCR reagents for both types of detection method and offer a range of master mixes designed to maximise your research output, ensuring reliable results and sensitive detection in every application.
